{{Short description|German audio hardware manufacturer}}
'''Doepfer Musikelektronik GmbH''' is a German manufacturer of audio hardware, mostly [[modular synthesizer|modular synthesizers]], based in [[Gräfelfing]], [[Upper Bavaria]], Germany and founded by Dieter Döpfer. The product range covers [[analog circuit|analog]] [[modular synthesizer|modular]] systems, [[MIDI controller]]s, MIDI hardware [[Music sequencer|sequencers]], MIDI-to-[[CV/Gate]]/Sync Interfaces, MIDI master [[Keyboard instrument|keyboards]] and special MIDI equipment.

Dieter Döpfer began developing audio hardware with a Voltage Controlled Phaser module for the Formant, a do-it-yourself-kit analog synthesizer from ''[[Elektor]]'' magazine in 1977. Several legendary modular synths followed while Döpfer also focused on the development of MIDI equipment during the 1980s. 

In 1992, Doepfer Musikelektronik GmbH released the MIDI [[analog circuit|analog]] [[Music sequencer|sequencer]] MAQ16/3 which was designed in cooperation with [[Kraftwerk]]. In the beginning, the company had direct sales and interested musicians would receive a demonstration by visiting other customers since the modular systems were deemed too difficult for typical music shop employees to demonstrate. Facing greater publicity, Doepfer shifted the distribution to specialized points of sales.
